Laid off this week, where do I start? after 14 years as a teaching assistant

They called a meeting on Tuesday and 14 of us were let go. I had been there 14 years. I have read a lot of threads here and could not find my exact situation. I have a box of my things and a short letter about benefits. Which steps were urgent?

File for unemployment right away. Do not wait for severance decisions. The date you file can matter.

I made a short list: benefits, bills, documents, and then my résumé. One thing each day kept me steady.
